Water Cooling Systems

Post  vderench on Sun Feb 08, 2009 9:21 am

I would like to ask folks to post any references to papers and articles or other types of publications they might know of that relate to corrosion in water systems. References to corrosion of copper and aluminum in DI water systems, corrosion and velocity for turbulent or non-turbulent flow, O2 content, or any other information relevant to corrosion in accelerator systems would be very useful.

Thanks, Laddie

Hi Laddie,

This paper looks to me one of the best I read on the subject : LOW-CONDUCTIVITY WATER SYSTEMS FOR ACCELERATORS from Dortwegt (APS - Chicago):
http://accelconf.web.cern.ch/AccelConf/p03/PAPERS/ROPB008.PDF

This one co-witen with Maughan, a reference in this field : THE CHEMISTRY OF COPPER IN WATER AND RELATED STUDIES PLANNED AT THE ADVANCED PHOTON SOURCE
http://accelconf.web.cern.ch/AccelConf/p01/PAPERS/TPAH106.PDF

This one was used at ESRF to better understand our problems : ACCELERATOR MAGNET PLUGGING BY METAL OXIDES
http://atk.web.psi.ch/8800/2004/Seite142_145_2004.pdf

And this one: Corrosion of Copper by Deionised Cooling Water
http://accelconf.web.cern.ch/AccelConf/e88/PDF/EPAC1988_1067.PDF

There are hundreds others papers but I think that those ones are a kind of references for a starting point.

Best wishes,

Laurent from ESRF

Another paper- analyses of copper absorbers at SSRL

Post  Cherrill Spencer on Thu Apr 02, 2009 2:59 pm

This 2005 SLAC Technical Note describes three different analyses of some synchrotron light absorbers in use at SSRL at the SLAC National Lab and shows the bad effects of a too high water velocity. It can be found here:

SSRL (SPEAR3 ring) components seem to be suffering more LCW corrosion than a few years ago and we have a task force set up to investigate this situation. I will report anything significant coming out of this task force here.
